I had an idea for a website: crowd-maintained list of downgrades for products, e.g. "Product: Twitter, Feature: login nag-wall when you scroll down. First Noticed: $month 2021,; Feature: killed the open API, Date: ___", etc. I still have the idea, if anyone wants to implement it, feel free.
Hell, it's fractal, all the way from major services to operating systems to the most minor app store apps. Products get better until someone decides they aren't growing fast enough and then they get worse until they die or someone sane realizes that your video file player doesn't need its own social network.
